Comment 1 for bug 1436647

I've added the 2 large object variables as ansible variables so these can be overwritten if you want.

I haven't changed the default chunk size though - the chunk is buffered in memory so I'm not sure that adjusting the default is a sensible idea - If your host has a large amount of memory then it may be fine but I don't think we should mandate that as a 1 size fits all best value.

Additionally, if swift is performing poorly that should probably be investigated it seems like swift shouldn't have an issue handling large amount of objects.
